GRAIN CLEANING AND WASHlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 369,768, datedSeptember 13, 1887. Application filed January 5,1887. Serial No.223,478. (No model.) Patented in England lTunc 19, 1886, Xo. 3,158.

To @Z6 whom, it may concern:

Be it known that I, JOHN IRELAND BOORER, a subject of the Queen of GreatBritain, residing at Liverpool, in the county of Lancaster, in theKingdom of GreatBritain, have invented certain new and usefulImprovements in Grain Cleaning and Washing Apparatus, (for whichprovisionalprotection has been obtained in England, dated June 19, 1886,No. 8,158,) of which the following is a specification.

This invention relates to certain improvements in machines for cleaningor washing grain or other seed, and is designed to prevent the casingfrom being choked up,to insure the better washing of the wheat, toenable the Wire covering to be easily cleaned, and foincrease theefficiencyof the rinsing of the grain.

Referring to the drawings annexed hereto, Figure I is a sectionalelevation of my improved machine. Fig. 2 is a plan with top removed.Fig. 3 is an end elevation.

In the drawings, A is the driving-shaft re volving in suitable bearings,a, which are tted in brackets attached to the tank B and provided with adriving-pulley, a2. This tank is constructed to hold a supply of waterand is fitted with a valve, b, to draw off the water when required.

C is a wire casing or cylinder partially submerged in the watercontained in the tank B. The two halves of the casing may be fastenedtogether at the center by any suitable means, so that one half may beeasily removable for the purpose of cleaning the inside or of repairingor removing the worm c or beaters c?, hereinafter described. Although Iprefer to make the casingin two halves, I do notlimit the inventionthereto.

The casing is constructed to revolve independently of'the shaft A,and isfurnish ed with suitable bearings, b', formed in the tankB.' The casingis fitted with wheels D,whioh gear with the wheel D, fixed on the shaftE. rIlhis shaft may be driven by the belt-pulleys F F. On the sameshaft, E, is fitted a brush, E, which brushes against the surface of thewire casing C and prevents the casing being choked. On the surface ofthe shaft A, inside the wire cylinder C, I form a worm,.c, theblades ofwhich may be extended, so as to form paddles or beaters c2, or acontinuous screw-thread may be used, if preferred, and on the ends ofthe shaft A the wormis extended to form thefeed and exit worms c3 c.They may either be fixed to the same shaft as the main worm or onsleeves revolving on the same independently. The water for washingpurposes is preferably forcedin by aninjector, H, through a centralchannel in the main shaft A and out through perf'orations in the same,as shown at 7L, near the exit endor conical part of the casing. Theheight of the water in the wire casing C may be regulated from one andone-halfto eight inches. In the old machines the height can only beregulated from one to two inches. The whole machine may be fixed onsuitable frames, L.

v'Ihe action of my machine is as follows: 'Ihe grain is fed into themachine through the hopper K by means of the feed-worm c3. As thebeaters c2 revolve at a different speed] from the n wire casing C, thegrain is thoroughly stirred up and washed in the hot water supplied bythe injector II. The action of the beaters will be also to feed thegrain toward the conical end of the wire casing C, which is notsubmerged in water. It now comes in contact with the fresh warm waterflowing through the jets 1L. As it rises still higher,it is drained bymeans of perforations into avessel or rinsingbox, M, from whence thedrainings are carnied away by the pipe m,and finally is drawn out of themachine by the exit-worm c* through the exit-spout N. The whole processis continuous.

Having now particularly described and ascertained the nature ofthe saidinvention,and in what manner the saine is to be performed, I declarethat what I claim isl. In a machine of the class described, the

combination, with a tank adapted to containl spectively, and beaterssecured to the shaft,

all substantially as shown.

2. In a machine of the class described, the combination, with a tankadapted to contain water, of a hollowshaft extending longi- IOC)tudinally through the same and provided with a water-supply pipe, aperforate casing also mounted within the tank, mechanism for impartingmotion to the casing and to the shaft, and beaters secured to the shaft,all substanstantially as shown.

3. In combination with tank B, provided with hopper K anddischarge-spout N, a shaft, A, provided with worms c* c3 and beaters c,a perforate casing, C, surrounding the shaft and mounted within thetank, and 1nechanism,sub stantially such as shown, for imparting rotarymotion to the shaft and tothe perfor-ate casing.

4. 1n combination with tank B,having hopper K and spout N, a perforatecasing,G, provided with a gear-wheel, D, a shaft, E, provided wit'h agear, D', to mesh with gear D, shaft A, provided with beaters vandlocated within the perforate casing, a band-wheel mounted on shaft A,and a belt for transmitting motion from shaft A to shaft E.

5. In combination with a tank, B, and a perforate casing mounted andadapted to rotate therein, a hollow shaft mounted within the perforatecasing,provided with lateral outlets h and with beaters c2, arrangedspirally about the shaft, a Worm at each end of the shaft, and mechanismfor imparting motion in opposite directions to the shaft and the casing.

6. In combination with tank B and a rotatable perforate casing C,mounted therein, a hollow shaft provided with beaters and worms andadapted to be rotated in a direction reverse to that of the casing, anda brush arranged, substantially as shown and described, to rotate inContact with the casing.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.
